Simple Memory MCP

English

Overview

Simple Memory MCP is a memory management system designed for AI assistants, implementing the Model Context Protocol (MCP) to provide persistent memory storage and retrieval capabilities.

Common Usage Methods-Features

1. Open Web Management Interface

Tell your AI assistant: "Open memory" or "Open memory WEB", the AI will:

Automatically start the web server
Open the default browser
Display the visual management interface

2. Get Memory List

Tell your AI assistant: "Get all memories" or "Show memory list", the AI will execute the list_memory_titles tool to retrieve all memory titles.

3. Get Specific Memory Content

Tell your AI assistant: "Get 'XXX' memory content and execute", the AI will execute the get_memory_by_title tool to retrieve the complete content of the specified memory.

4. Store New Memory

Tell your AI assistant: "Help me store a memory", the AI will:

First ask you to provide the memory title
Then ask you to input the memory content
Execute the store_memory tool to complete storage

Features

Smart Memory Storage: AI assistants must first ask users for memory titles, then request content
📋 Efficient Retrieval: Optimized MCP tools return only essential data (title + timestamp) for better performance
🌐 Web Management Interface: Intuitive visual management with full CRUD operations
🔍 Full-text Search: Search through both titles and content
🎯 Intelligent Port Management: Automatic port detection and conflict resolution
📱 Responsive Design: Optimized for both desktop and mobile devices
🔒 Single Instance Design: Automatic detection prevents multiple server instances
🤝 Multi-AI Support: Multiple AI assistants can safely share the same server instance

Run the installer (.msi file)
Follow the installation wizard with default settings
Restart your computer after installation

For macOS Users:

# Option 1: Download from official website
# Visit https://nodejs.org/ and download the LTS version

# Option 2: Using Homebrew (recommended)
brew install node

For Linux Users:

# Ubuntu/Debian
sudo apt update
sudo apt install nodejs npm

# CentOS/RHEL/Fedora
sudo dnf install nodejs npm

# Arch Linux
sudo pacman -S nodejs npm

Verify Installation:

# Check Node.js version
node --version

# Check npm version
npm --version

Both commands should return version numbers (e.g., v18.17.0 for Node.js).

# Install dependencies
npm install

# Initialize database
npm run init-db

Start Services

# Start MCP Server
npm start

# Start Web Interface (recommended)
node start-web.js
# or
npm run web

Access Web Interface

Default URL: http://localhost:8011
The system will automatically detect and allocate available ports

AI Assistant Configuration

Universal Configuration Template

Use the following configuration template for any AI assistant that supports MCP:

{
  "mcpServers": {
    "simple-memory": {
      "command": "node",
      "args": ["./start-mcp.js"],
      "cwd": "/path/to/your/simple-memory-mcp"
    }
  }
}

Configuration Steps:

Replace /path/to/your/simple-memory-mcp with your actual project path
Add this configuration to your AI assistant's MCP settings file
Restart your AI assistant to load the new configuration

Note: The start-mcp.js script provides better error handling and user-friendly output compared to directly calling src/server.js.

🔒 Single Instance Design

Simple Memory MCP uses a single instance design to ensure optimal resource usage and data consistency:

Automatic Detection: Before starting, the system checks if an MCP server is already running
Smart Sharing: Multiple AI assistants (Claude, Augment, etc.) can safely share the same server instance
Resource Efficiency: Prevents duplicate server processes and database conflicts
Seamless Experience: If a server is already running, new AI connections will automatically use the existing instance

Multi-AI Workflow:

First AI starts → Detects no server → Starts new MCP server → Connects successfully
Second AI starts → Detects existing server → Shows friendly message → Connects to existing instance
Both AIs can use memory functions simultaneously without conflicts
When all AIs close → MCP server automatically shuts down to free resources

Usage Examples

Through AI Assistant

User: Help me store a memory
AI: Please provide the title for this memory:
User: Study Notes - MCP Protocol
AI: Please enter the memory content:
User: [Enter content]
AI: Memory "Study Notes - MCP Protocol" has been successfully stored!

NEW! Web Interface Auto-Launch

Simply say any of these trigger phrases to your AI assistant:

"打开记忆MCP" (Open Memory MCP)
"打开记忆" (Open Memory)
"打开记忆WEB" (Open Memory WEB)
"开启记忆" (Start Memory)

The AI will automatically:

🚀 Start the web server (if not running)
🌐 Open your default browser
📋 Display the memory management interface
✨ Provide usage tips and access URLs

Through Web Interface

Click "➕ Add Memory" to create new memories
Click memory cards to view details
Use action buttons on each memory card:
- Edit (🖊️) - Modify memory content
- Copy (📋) - Copy title and content to clipboard in plain text
- Delete (🗑️) - Remove memory permanently
Use the search box to find specific content
Drag and drop memory cards to reorder them

MCP Tools

store_memory - Store new memory (requires title and content)
list_memory_titles - Get list of all memory titles
get_memory_by_title - Retrieve memory content by title
delete_memory - Delete specified memory
open_memory_web - NEW! Open memory management web interface with auto browser launch

# Ubuntu/Debian
sudo apt update
sudo apt install nodejs npm

# CentOS/RHEL/Fedora
sudo dnf install nodejs npm

# Arch Linux
sudo pacman -S nodejs npm

验证安装：

# 检查Node.js版本

AI助手配置

通用配置模板

以下配置模板适用于任何支持MCP的AI助手：

{
  "mcpServers": {
    "simple-memory": {
      "command": "node",
      "args": ["/path/to/your/simple-memory-mcp/start-mcp.js"],
      "cwd": "/path/to/your/simple-memory-mcp"
    }
  }
}

配置步骤：

将 /path/to/your/simple-memory-mcp 替换为你的实际项目路径
将此配置添加到你的AI助手的MCP设置文件中
重启你的AI助手以加载新配置

注意：start-mcp.js 脚本相比直接调用 src/server.js 提供了更好的错误处理和用户友好的输出信息。

🔒 单实例设计

Simple Memory MCP 采用单实例设计，确保最佳的资源使用和数据一致性：

自动检测: 启动前系统会检查是否已有MCP服务器在运行
智能共享: 多个AI助手（Claude、Augment等）可以安全地共享同一个服务器实例
资源高效: 防止重复的服务器进程和数据库冲突
无缝体验: 如果服务器已在运行，新的AI连接会自动使用现有实例

多AI工作流程：

第一个AI启动 → 检测无服务器 → 启动新MCP服务器 → 成功连接
第二个AI启动 → 检测到现有服务器 → 显示友好提示 → 连接到现有实例
两个AI可以同时使用记忆功能 而不会产生冲突
当所有AI关闭时 → MCP服务器自动关闭以释放资源

使用示例

通过AI助手使用

用户: 帮我存储一个记忆
AI: 请提供这个记忆的标题：
用户: 学习笔记 - MCP协议
AI: 请输入记忆的具体内容：
用户: [输入内容]
AI: 记忆 "学习笔记 - MCP协议" 已成功存储！

新功能！Web界面自动启动
